Hi all just looking for answers!!

I had lots of different kinds of chickens as a kid just bought some chicks.
What I thought were black sex links
But a lot of them are brightly colored with purple and green feathers and curving tail feathers I am afraid I have something else
(As far as breed) and sex I sooo hope I am wrong but I do remember sexing chicks when I was a kid and I think about 7 of my 20 are roosters
They are heavier, bigger combs and waddles
And very shiny feathers and they are "mock"
Fighting with each other ughhh!!
So I Put up some pics of three of them happy to take more if anyone cares to guess!
Thanks!!

Thanks
Everybody has been so helpful this is my first
